Rockwool insulation boards primarily use natural ore as the main raw material. Here are the performance characteristics of rockwool insulation boards:
Rock wool insulation board has a hard and strong surface with excellent weight-bearing capacity. Not only is it resistant to impact, but it also offers great wind resistance.
It boasts exceptional chemical stability, capable of withstanding high temperatures, acidic and alkaline conditions, and resistance to aging, making it a durable product with an extended service life.
Efficient and labor-saving, the installation process is incredibly simple and straightforward. Utilizing modular or assembly installation methods, the construction can be completed quickly.
Rock wool board external wall thermal insulation system boasts advantages such as low thermal conductivity, good breathability, and excellent combustion performance. Let's take a look at the composition of the rock wool external wall system and its applications.
Firstly, the mineral wool exterior wall system is primarily composed of the bonding layer, insulation layer, finish coat layer, decorative layer, and accessories. The decorative layer should be made of lightweight functional coatings such as decorative mortar or decorative slurry, or a water-based exterior paint with good breathability. Secondly, the mineral wool exterior wall system can be applied to energy-saving insulation projects on the exterior walls of residential and public buildings, including external wall insulation, non-transparent curtain wall insulation, and fire separation strips for EPS external insulation systems.
Due to its high water absorption, high energy consumption in material production, low inherent strength, and significant dust damage during construction, rock wool board manufacturers have not been able to widely promote its use in external thermal insulation. In recent years, the introduction of the pendulum method of production and fiber surface treatment technology has greatly improved the comprehensive performance of rock wool boards. Rock wool is an inorganic material made by spinning and bonding after calcination, with a thermal conductivity of approximately 0.044W/m.k, low compressive strength, and open-cell fibers that offer good breathability. Surface treatment provides it with certain waterproof and moisture-proof properties for external thermal insulation grade rock wool boards. However, its bonding strength with the wall base is poor, and the rock wool board surface must be treated with an interface agent before use. It also requires high performance in bonding and crack-resistant mortar.
